ROBERT C. SOHREIBER, OF FAIRMONT, MINNESOTA.

ROAD-SMOOTHER.

Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed July 12, 1906. Serial No. 325,954.

To (bi/Z whom, it Duty concern.-

Be it known that 1, ROBERT C. SOIIREIBIER, a citizen of the U'eited States, residing at Fairmont, in the county of Martin, State of Minnesota, have invented certain new and useful Improvements in Road-Sincethers;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to road-smoothers, and has for its object to provide a smoother which will both pack the road and scrape the loose surface -earth and roughncses therefrom, another object being to provide a smoother which will be simple and durable a: :d which will include a novel arrangement of parts.

It is to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

In the drawir s forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a top plan view of the present inventlen. Fig" 2 is a side elevation. F 3 is a rear elevation. Fig. 4 is a lorgitudinal section on line r 4 of Fig. 1 taken longitudinally of the drum.

Referrill now to the drawip s, there is shown a t gue 5, to the rcar\ trd end of which there are secured a pair of o}'\positely extending horiz;urtally-disposed rectargular frames thircluding fl'OIlll and rear members 7 and end m -nbers S, the inner end members beir secured to the tongue. liegisteri; bear rig-openings 9 are iormed in the end members for the reception of axles 10, upon which are fixed presscr-rollers 11, having series of peripheral calks 12, arranged in tortuous lorgitudinal lines. A whil'llctree 13 is pivoted upon the toiigue and has its ends connected with the fcmvard members 7 of the frame 6 by means of chairs 1.4, which thus limit the pivotal movement of the whiflletree, and sirgletrees 15 are carried by the e:: ds of the whi'llletree. Yokes 16 have stems 17, which are secured to the forward members 7 of the frames, the yokes beitfg curved rearwardly and downwardly over the rollers and havir g the rearward ends of their legs secure d to rearwardlyconvergent scrapers 18, disposed to engage the ground in the rear of the rollers. The stems 17 are pivoted to the members 7 for vertical movement of the scrapers 1S, and the legs 16 of the yokes 16 are connected by cross-pieces 19, having upwardly-extending rods 20 secured thereto. liearwardlyextending arms 21 are secured to the forward members 7 of the frame and are curved to bring their rearward portions beyond the rollers, as shown, and dependii rack-bars 22 are carried by the rearward ends of these arms. Lovers 23 are pivoted to the arms 21 and to the rods 20 for vertical movemei'rt of the yokes and scrapers when the levers are moved, and a hand-operated latch mechanism 241 is car ried byeach lever 23 and arranged for engagement of the respective rack-bar 22 to hold the scraper in ditl'erent positions with respect to the ground.

It will thus be seen that the rollers 11, which are of considerable weight, will press the ground which they pass over and that the calks 12 will crush the surface unevennesses to facilitate the scrapin of the road by the scrapers 18, the latter bein movable into and out of operative position, as will be readily understood.

\V hat is claimed is- 1. A smoother con'rprising a tongue, oppositely-extendingfram es secured to the tongue, rollers jourzrz'tled in the frames longitudinally thereof, scraper-supports pivoted to the frames forwardly of the rollers and extending rearwardly and downwardly thereover, scrapers secured to the supports in the rear of the rollers, arms secured to the frames, levers pivoted to the arms, connections between the levers and the scrapers for movement of the latter into and out of operative position when the levers are moved, and urea s for holding the levers at different points of their movement.

2. A smoother comprising a tongue, oppositely-exteiuling frames secured at their inner ends to the rearward portion of the tongue in horizontal position, said frames including end members and forward and r ar members,

axles journaled in the end members, drums fixed upon the axles and having peripheral calks, stems pivoted to the forward members of the frames, yokes carried by the stems and extending downwardly and rearwardly beyoud the frames, rearwardly-convergent scrapers carried by the yokes, cross members connected to the legs of each yoke, rods carried by the cross members, rearwardly-exrack-bars to hold the scrapers at diflerent 1o tending arms secured to the forward mempoints of their movement.
